Specification of Letters Patent.

Patented May 8, 1906.

Application filed February 18, 1903- Serial N- 143,942.

To all whom it may concern.

Be it known that I, SAMUEL L. ALLEN, a citizen of the United States, anda resident of Moorestown, State of New Jersey, have invented certain newand useful Improvements in Cultivators, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to certain improveto that class known aspivot-wheel walkingcultivators. S

The objects of my invention are, first, to provide a simple inexpensivemachine of the type stated and to generally improve its construction andefficiency; second, to provide a pivot-wheel cultivator havinghandle-bars for the use of the operator in steadying the machine, whichalso serve as levers, one for raising and lowering the gang-frame toregulate the depth of penetration of the teeth into the soil and theother serving to turn the pivot-wheels for the purpose of steering themachine, and, third, in providing an improved form of supporting-frameand gang together with improved means for attaching the shafts of themachine.

With these objects in view my invention consists in the construction,arrangement, and combination of parts, such as will be fully set forthhereinafter and particularly noted in the claims made hereto.

Referring to the accompanying drawings, Figure 1 is a plan view of acultivator constructed in accordance with my invention. Fig. 2 is a sideelevation of the same, the teeth of the gang being shown as entering theground; and Fig. 3 is a detail section illustrating the end of thegang-frame.

In carrying out my invention 1 rovide a main frame 1, which issubstantial y rectangular in form, consisting of the side bars 2 and 3and the transversely;clisposed front bar 4 and a transversely-disposedbar 5, located a short distance in rear 01 the front bar and connectedat its ends to the side bars 2 and 3. To the rear ends of the two sidebars 2 and 3 are ri idly connected the twin bars 6 and 7, which orm thegang-frame. The upper bar 6 of the gang-frame comprises a flat steel.bar having its ends turned down, as illustrated at 8, while the lowerbar 7 is channel-iron or steel and has its ends turned up, asillustrated at 9' in Fig. 3 of the drawin s, so that when the two barsare assembled the ments in cultivators, and more particularly j .bar ofthe main frame.

depending section 8 will fit into the channel of the section 9. Thesetwo parts are bolted to the side bars by the bolt 10, as illustrated.The lower channel-bar 7 is adapted to carry thel clamps 11, whichsupport the tool-standarr s.

The pivot-bars which carry the supporting-wheels 12 comprise thevertically-disosed bar 13, having its lower end curved and bent atsubstantially right angles to the section 13, as illustrated at 14, thesection 14 serving as the axle for the supporting-wheel. A box 15 issecured around the lower section of the pivot-bar, and resting on thetop of this boxing is an arm which forms a part of thevertically-disposed b r 16, which is bolted to an angle-bar 17, securedto the cross- The upper end of the bar 16 is bent at substantially rightangles and forms a bearing for the u per end of the pivot-bar 13. Abrace-rod 18 is provided for further supporting the pivot-supporting bar16, which is secured at its lower end'by means of a bolt 19 to the lowerportion of the bar 16 and at its upper end to the front framebar 4 bymeans of the bolt 20.

Secured to each of the pivot-bars 13 are the rearwardly-extending arms21, Which have secured to their free ends a connecting-bar 22. Thisconnecting-bar 22 is provided with a series of apertures 23, adjacenteach of its ends, so as to allow the pivot-bars to be adjusted laterallywhen it is desired to Widen or narrow the tread of the Wheels. Pivotedabout in the center of the connecting-bar 22 is a link 24, which ispivoted at its other end to a lever 25, which is in turn pivoted to abearingblock 26, secured on the bar 6 of the gangframe. This lever 25 isbolted to the handlebar 27, and by moving the said handle-bar laterallythe pivot-bars and their wheels may be turned in either direction forthe purpose of steering and guiding the machine. For'the purpose ofkeeping the handle-bar 27 steady a pin 28 is provided whichpasses'through an aperture formed pivot and through a projecting lug 29,carried by the bearing-block 26. When it is desired to move the lever 27laterally to turn the pivot-wheels, this pin 29 must of course beremoved. i

The shafts are provided at their rear ends with the irons 31, havingeyes provided in their free ends which fit between the clips 32, formedin the front corners of the main frame, and the pivot-bolts 33, carriedthe in the lever 25 in rear of its" clips, pass through the eyes of theirons 31,

erebysecuring the shafts to the main frame. In the center of the frontframe-rod 4 are the angle-irons 34, rigidly secured to the rear side ofthe said frame, and between these angleirons is secured a segmental rack35, which-issupported on the bolt 36, carried by the angle-irons. Thissegment 35 has rigidly secured to its lower portion an arm 37, whichextends forwardly and is then curved upwardly and secured to the underside of the cross-bar 38 of the shafts by means of the bolt 39, so thatthe said segment 35 is rigid with the shafts. Pivoted on the bolt 36 arethe levers 40 and 41, which are bent at a slight angle and have theirrear ends rigidly secured to the handle-bar 42. The lever 40 is providedwith a springpawl 43 of the usual construction, ch is operated by a rod44, which extends to the rear end of the handle-bar and is provided witha pivoted operating-handle 45 of the usual construction. Pivoted to thebolt 36, adjacent the levers 40'and 41, is a brace-bar 46, which isinclined downwardly and rearwardly, and has its other end rigidlysecured .between the two bars 6 and 7 of the gangframe and which servesthe purpose of strengthening the main frame and making the same veryrigid.

Secured to the upper bar of the gang-frame 6 is a bar 47, which extendsupwardly and through a slot provided in the handle-bar 42 and is securedto the said handle-bar by means of a bolt 48, which passes through thehandle-bar and through an elongated slot 49, provided in the upperportion of the bar 47. A collar or clip is rigidly secured on the bar 47some distance above its connection with the gang-frame, and inter osedbetween this clip and the under side 0 the handle-bar 43 is a coiledspring 51, which exerts its tension on the gang-frame and at the sametime allows or admits of the said gang-frame yielding in an upwarddirection in the event of the teeth coming in contact with stones orother obstructions in the ground.

In the operation of my machine it will be readily understood that byoperating the lever 42 the gang-frame and its toolsmay be raised orlowered and held in adjusted position by means of a rack-and-pawlmechanism, and the frame may be also lifted, so that the teeth willclear the ground during transportation to and from the field. This lever42, together with the lever 27 ,perform a double functionthat is to say,they serve as handle-bars for the use of the operator in steadying themachine, while the handlebar 42 serves as a lever for raising andlowering the gang, as above described, and the handlebar 27 serves as alever for turning the pivot bars which carry the supporting-wheels whenit is desired to guide the machine in either direction, this beingaccomplished by means of the connecting-bars which connect the saidleverwith the pivot-bars. The lever 42 may also be used to regulate theheight of the shafts to suit the horse, as the segment 35 is pivotallymounted on the bolt 36 and rigidly connected to the cross-bar of theshafts by means of the bar 37, so that after hitching up the horse theheight of the front part of the shafts can be regulated by the operationof the lever 42. It will also be noted that the entire frame issupported on the pivot-bars and swings on the axle formed by the loweror horizontal portion of said pivot-bars. The construction of the frameis very simple and inexpensive to manufacture, while at the same time itpossesses great strength and durability, and the entire machine is veryeflicient in its operation.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In an agricultural implement, the combination with a main tool-frameand a draft means hinged to the forward part of said frame, of a leverpivoted to said main frame, means for maintaining said lever in apredetermined position with respect to said draft means for adjustingthe angular relation between said draft means and said tool-frame, andmeans connected to said lever and said tool-frame for permitting saidframe and lever to yield with respect to each other.
